UNITED STATES PATENT OFFICE- GARLE MANNING FULLER,'OF KIRKSVILLE, MISSOURI.

. siding at Kirksvi'lle, in the tachably connected .AUTOMOBILE-RAIDIATOR CAP.-

To all whom it may concern:

Be it known that I, GARLE MANNING FULLER, a citizen of the United States, re-

county of Adair and State of Missouri, have invented a new and useful Automobile-Radiator Cap, of which the following is a specification, referdrawings and to the letters and figures. of reference marked thereon. This invention relates to a closure sels or containers and especially for automo:

v bile radiators and fuel tanks, the invention having reference more .particularly to a quick-action closure and one having a lock to prevent accidental unclosing operation- .thereof.

An object ofthe invention is to provide a time-saving closure appliance which shall be so constructed as to permit rapid operation thereof and without requiring the use of tools to effect'operation.

Another object is to provide an improved quick-action closure which shallbe so constructed as to operate effectively and not become loose inuse although the parts thereof may not be forced tightly together, which closure shall be ofsimple and inexpensive construction, and which shall be durable and economical in use. Y

r A further object is to provide a radiator -.or fuel tank cap which shall be so constructed as to be enabled to be securely.

locked in place against accidental dislodgment, and which shall be adapted to be manipulated easily and in a simple manner, and especially when the attendant is wearin gloves in cold seasons.

' Vith the above-mentioned and otherv objects in view, the invention consists in .a quick-action closure having novel ,features, of construction embraced 1n two principal parts whereby one of the parts may be de quickly to the other part; and, the invention consists also further in the parts and combinations and arpreferably rangements of parts as hereinafter particu: larly accompanying claims.

Referring to the drawings, Eigure 1 is an elevation of the improved closure as constructed and'in its relation 't0 an automobile radiator indicated bybroken lines;,Fig. 2 is a vertical central sectionof .theclosure as preferably constructed; Fig.-

9 is an inverted plan of the cap part slightly modified as in Fig. 8; and, Fig. 10 is a top plan of the neck and mouth part of the closure as modified.-

Sim1lar referencecharacters in the differ-' ent figures of the drawings indicate correspondlng elements or features of construetion herein referred to in detail.

In the drawings the numeral 1 indicates the upper portion of a vessel, more specifi- ,6 on the inner portion thereof. .The upper end ortop of the wall is flat to constitute. a joint-face from which extends a. guide bore 7, a relatively smaller guide boreES extendlngfrom the bore '7, and the wall. has an aperture" 9 extending'from the-surcally an automobile radiator, and one 'prina cipal part of the closure is suitablysecured. permanently thereto, being a neck and.

face to'the guide bore 7. A cylindrical lock bolt 10 is provided which is guided in the extending through the bore 8, the bolt having 'a beveled tooth 12 thereon that projects beyond the joint face ofthe wall. A lug pin 13 is movably arranged in the a ertur'e] 9 and secured to the lock bolt 10 an it has a finger plate-or slide "14 secured thereto which is ada ted to slide on the surface of the wall and as transverse teeth 15 and 15,' to prevent the finger or thumb from 'slipping'and to enable the slide tobe pushedby a gloved hand, the finger piece being of ample dimensions so as to afford ample bulk for operation in the darkness of night and l with a love on the hand of the at'tendant. The l'oc bolt is automatically projected by means of'a coil spring 16 seate 'in the bore I the lock bolt 1s preferred.

7 andviagainst the inner end of the lock bolt, the spring encircling the stem 11 when The cap part-comprises an-annular body portion or cylindrical wall 17 and, in case the wall portion 4 has the ribs on its inner side and is provided with the lock bolt, the

, body portion 17 is adapted to be received notches with ratchet-like action to prevent the cap part from turning backward if jarred looseby the vibrations of the automobile.

In some cases the arrangement above described may be reversed, in which case'the mouth part or wall 4' has no lock bolt but the-joint face thereof has two series of notches 21' and 22 to receivev the beveled tooth 12 of the lock bolt which is arranged in a guide bore 7 i in a relatively thick wall portion 23 with which the cap part is provided, a small guide bore 8 extendingfro'm the larger guide bore and the wall having an aperture 9 therein in which the lug pin.

13 is arranged and having the finger plate 14 thereon. The cap part has a closure Web 24' in its upper portion which has suitable lugs 25 thereon wherebyto easily turn the cap part.

Y In some casesan elasticcushion ring 26 is arranged between the flange portion 3 and the'body portion 17 of the cap part to prevent rattling in case the joint-faces are not" solidlyin contact when the ratchet tooth enters one'of the lock notches,,whe n the appliance is used as'a radiator cap, or to operate as a packing in case an air-tight joint is requiredL 'In practical use the finger plate 14; is read ily moved to retract the lock bolt "and. permit the cap part to be turned, a portion of a (complete revolution only being necessary .to I release the cap-part from the mouth part of thefclosure.

In an automobile radiator cap, the combination, with two cooperating parts to be rotatively connected together one upon the-- other, andribs on the parts cooperatin to hold the parts-together, the upper'one o the parts having a closure in its top, each part having an annular joint-face to be engaged one by the other,'the-joint-face of one of the parts having notches therein, of a cylindrical lock bolt slidingly inserted in the otherof said parts tobe projected into one of said notches, the lock bolt having a rigid lug pin on one side thereof-that extends laterally beyond the outer side of said part,

and a broad finger plate slidingly arranged. on the said outer side and secured lug pin.

to said 2. In an automobile radiator cap, the

combination of a neck and mouth part comprising an annular base portion, an out-.

wardly-extending flange on said portion, an

upright cylindrical ,wall on said flange, the

top of said wall being a joint-face and the wall having a guide bore extending from the I joint-face and approximately to the planeof said flange, said Wall having also a slot extending transversely from said guide bore, a- 7 spring seated in said guide bore, a cylindrical lock bolt in said guide bore and upon said spring, the outer end of said .bolt having a beveled tooth thereon, a lug pin-fixed on one side of said bolt and-extending through said slot,ftwo inclined ribs spaced apart on the inner side of said wall, and a broad finger plate arranged to slide on the outer side of said wall and secured tosaid pin,

the front of said plate having transverse, teeth thereon; and a cap part comprising inserted in said wall and having fan out-- wardly-e xtending portion ada ted to conon said wall, the "joint-face of the outwardly-extending portion having transverse notches, a closure web in the top of said body portion, lugs on the top of said web,

and two separate inclined'ribs on the outer side of said body portion.
